Options

  1. ARose has superior ovary while China rose has inferior ovary
  2. BRose has inferior ovary while China rose has superior ovary
  3. CRose has semi-inferior ovary while China rose has inferior ovary
  4. DRose has semi-inferior ovary while China rose has superior ovary

Correct answer

D. Rose has semi-inferior ovary while China rose has superior ovary

Step-by-step solution

Rose has perigynous flowers in which the gynoecium is present in the center and other whorls of the flower are located on the rim of the thalamus almost at the same level. Thus, it has a semi-inferior ovary. China rose has hypogynous flowers in which all the floral whorls are attached below the gynoecium. Thus, it has superior ovary.
